DESCRIPTION

In 2004, our team delivered one of the first flat-plate MBR systems in the U.S. at McKinney Roughs, a compact, stainless-steel MPAC package plant rated for 25,000 GPD. Twenty years later, the site needed a longer-term solution at far greater scale. NXT|MBR delivered it: a 250,000 GPD system, 10x the original capacity, using membranes three times more efficient than the 2004 technology, built on CROM² concrete tankage engineered for a 50+ year service life. McKinney Roughs also marks how far MBR has come as a technology. Once chosen mainly for its small footprint and high effluent quality, MBR now competes on total cost of ownership. The 250,000 GPD system was awarded through a competitive bid and reportedly 30% below alternative technologies. The site can accommodate expansion up to 750,000-GPD as demand grows.
As an experienced - and engagingly impartial and self-effacing - practitioner in the field of MBR technology, Dennis seems to know heaps more about the subject than most of the senior academics I’ve met over the course of the past 25 years.
